Simple relations between protonic conductivity ($\sigma$) and the peak wave number (${\nu }_{\mathrm{OH}}$) of O-H infrared absorption band, and between activation energy for the electrical conduction and the wave number (${\nu }_{\mathrm{OH}}$) were found in oxide glasses containing no alkali- and/or transition-metal ions. The present investigation enables one to evaluate the protonic conductivity and the activation energy at a unit proton concentration of a given glass specimen from an ir spectrum of the glass plate, respectively.
